Embodiment Construction

[0015] The technical solutions of the present invention will be described in further detail below in combination with specific embodiments according to the drawings in the description.

[0016] Without changing the structure of the existing substation automation system, the present invention adopts the strategy of virtual point mapping dual measurement and control actual data, realizes the access of dual measurement and control data, that is, provides a layer of intermediate data (virtual point), and connects primary equipment with dual measurement and control Device isolation ensures that the primary equipment information that operators are concerned about is unique. The main contents are:

[0017] For the primary equipment of the substation, establish corresponding virtual point data such as virtual telemetry, virtual remote signal, and virtual remote control in the automation system. The analog signal of the primary equipment corresponds to virtual telemetry, the position si...

Abstract

The invention discloses an implement method of an electric substation automation system for supporting double measurement and control. In the design of a normal transformer station with voltage levels of 220KV and above 220KV, a measuring and controlling device and two protecting devices are arranged in one interval, and a single measuring and controlling device aims at the measurement and the control of a primary device. Along with the appearance of voltage step protection of 220KV and above 220KV and a measuring and controlling integrative device, a double protection / measuring and controlling integration device is configured in engineering, and thus, the problem to process data of the double measuring and controlling device by a transformer station automatic system occurs in. On the basis of unchanging the structure of the prior transformer station automatic system, a strategy of mapping double measuring and controlling practical data by virtual points is adopted to realize the access of the double measuring and controlling data.

Description

technical field [0001] The invention belongs to the technical field of electric power system substation automation, and in particular relates to a method for realizing dual measurement and control of a substation automation system. Background technique [0002] In conventional substation design, generally only one measurement and control device and two protection devices are configured in one interval for voltage levels of 220kV and above. In the interval of 110kV and below, generally only one measurement and control device and one protection device or an integrated measurement, control and protection device are configured. In the above configuration, a single measurement and control device is used for the measurement and control of primary equipment. Therefore, the existing substation automation systems generally do not have the ability to handle dual measurement and control devices for primary equipment. [0003] With the emergence of integrated devices for measurement, c...
